|More information about the OAD will be revealed in the ninth issue of the Weekly Shōnen Magazine. It was, however, already implied, that this ninth issue will contain a "super important announcement" concerning the series.|
The 28th compiled volume is expected for mid-May.
Kouji Seo's manga, which is published since 2008 in Japan, already featured a two-part OAD in early 2012. In summer last year a TV anime adaption, consisting of twelve episodes, has been released.
As previously announced, another two OAD episodes will air on January 17th and March 17th, this year.
